Abstract

A ventilator including an inspiration flow control unit and an expiration flow control unit coupled to the inspiration flow control unit. The ventilator also includes a nasal intermittent mandatory ventilation (NIMV) control system coupled to the inspiration flow control unit and the expiration flow control unit. The NIMV control system is configured to automatically and simultaneously adjust an inspiration flow and an expiration flow. A pressure of the inspiration flow is increased from a baseline pressure to a control pressure. A pressure of the expiration flow is returned to the baseline pressure.
